摘要
通过成渝客运专线新中梁山隧道与既有襄渝线中梁山隧道交叉跨越段方案设计,系统性地介绍交叉段的加固方案,包含既有隧道二衬的加固措施和新建隧道的开挖支护,并通过有限元分析与结构强度检算,证明了加固方案的可行性。
Based on the scheme design for the intersection spanning between the new Zhongliangshan Tunnel of Chengdu-Chongqing Passenger Dedicated Line and the existing Zhongliangshan Tunnel of Xiangfan-Chongqing Railway, the article introduces the strengthening scheme of the intersection point systematically, including the strengthening measures for the secondary lining of the existing tunnel, the excavation supporting for the new one. Through the analysis and calculation on the structural strength by finite element method, the feasibility of strengthening scheme has been verified.
